The Q-Pipe (now also available as a Q-Box) Flameless Vent System was developed in response to a specific need, i.e. explosion venting inside buildings. Traditional explosion venting technologies require a safe venting area (usually outdoors), where there is no risk of secondary explosions or harm to personnel. Explosion vented plant has to be ducted out to a designated (external) safe area (usually within 3 to 6 metres). The only alternative was to strengthen vessels to withstand greater explosion pressures and/or to install relatively expensive explosion suppression systems.

To meet the need ATEX developed its clean out technology in a passive oriented system. A valve that could meet the product flow requirements of today’s processes. The system would by Patent Pending Design clean out the isolation seal eliminating consideration of powder being compressed by the closure and allowing flame to pass.
